  Log:
  Add code to ddb to allow backtracing an arbitrary thread.
  (show thread {address})
  
  Remove the IDLE kse state and replace it with a change in
  the way threads sahre KSEs. Every KSE now has a thread, which is
  considered its "owner" however a KSE may also be lent to other
  threads in the same group to allow completion of in-kernel work.
  n this case the owner remains the same and the KSE will revert to the
  owner when the other work has been completed.
  
  All creations of upcalls etc. is now done from
  kse_reassign() which in turn is called from mi_switch or
  thread_exit(). This means that special code can be removed from
  msleep() and cv_wait().
  
  kse_release() does not leave a KSE with no thread any more but
  converts the existing thread into teh KSE's owner, and sets it up
  for doing an upcall. It is just inhibitted from being scheduled until
  there is some reason to do an upcall.
  
  Remove all trace of the kse_idle queue since it is no-longer needed.
  "Idle" KSEs are now on the loanable queue.
